Unfortunately, no. Toothbrushing, whether you use a manual or electric brush, is a very technique-dependant process. In other words, how much plaque you take off from your teeth really depends on how you brush. In fact, many of us don't brush as well as we think we do (hence the high prevalence of gum disease among adults). Children, older adults, and people with disabilities may also face additional challenges with dexterity or a brushing routine.
